SMAW-NE

"War is hell. But it’s worse when the Marines bring out their new urban combat weapon, the SMAW-NE. Which may be why they’re not talking about it, much.

This is a version of the standard USMC Shoulder Mounted Assault Weapon but with a new warhead. Described as NE - "Novel Explosive"- it is a thermobaric mixture which ignites the air, producing a shockwave of unparalleled destructive power, especially against buildings."
